Wait a minute, here. This is something that has been thrown about on this thread fairly often, and it just doesn't ring true.
Apple did update 6. It is 6.1.6. Just because 6.1.6 is not available for your device doesn't mean that Apple is not supporting 6.
There are currently 11% of all iDevices using iOS 6. I am willing to venture a bet with you that the majority of that 11% are 3GS's or 4th generation iPod Touches, and that only a small minority of that 11% are devices capable of running iOS 7. I would even go so far as to suggest that of that small minority, that the vast majority of those users simply don't know or care about an update and that only a very small minority of that small group (I would venture a guess that actual percentage is measured in the thousandths or hundredths of a percent) are refusing to upgrade on purpose for whatever reason, be it aesthetics or performance issues, etc.
My point is, Apple has made a decision to support as many devices as possible with the latest software, to keep its user base safe and secure, and have access to as up-to-date software and features as possible - this in contrast to ALL other mobil OS suppliers currently out there on the market. They do this in a very simplified way, so that the average consumer only has to follow a couple of prompts and tap their device a couple of times to stay updated. They don't have to go to a website, search through a bunch of different version numbers, find the right one for their device, risk bricking their phone, deal with SHSH blobs, root directories, etc.
I guess you would rather that only the newest devices were allowed to use the latest software instead? Or that iOS was like Android in the sense that the user was one their own as far as updating their software, because the hardware manufacturer doesn't or can't provide support for the software?
Apple is not twisting your arm to stay a customer. If you don't like it, you are welcome to switch platforms. The vast majority of Apple customers disagree with your view, and you might be better off moving to a different platform.
